摘　　要：高分辨率遥感已成为矿山环境调查的重要手段。由于矿山地形起伏引起的像点位移使得常规的几何校正难以消除影像的几何变形,必须进行正射校正。与传统的正射校正相比,ERDAS LPS下的正射校正可以减少全野外布点和测图工序,自动生成内外方位元素,在同等精度条件下提高了作业效率。在实验区,根据项目的要求提出LPS模块下正射校正的流程,基于Spot5物理模型分别对全色和多波段影像进行正射校正,结果完全满足精度要求。Remote sensing images with high resolution become an important means of the environmental investigation of mines.Because of the displacement of image caused by topographical relief,it is difficult for conventional geometric correction to eliminate the geometric distortions of image.Comparing with conventional orthorectificafion,the orthorectificafion based on ERDAS LPS can decrease outdoors sampling spots and plotting working procedure,automatically produce elements of orientation,and improve the working efficiency.According to the project requirement,a feasible process of orthoreetification using LPS model was put forward.And the orthoreetification of panchromatic and multi-spectral images of the investigated area based on the physics model of Spot5 was carried out,the experiment results satisfied the request of accuracy.
